In spite of its high temperature, the corona yields relatively little heat, because of its low density; i.e., the constituent gas molecules are so sparse that the energy content per cubic centimetre is substantially lower than that of the interior region of the Sun. Solar prominence This allowed much more data to be downlinked. developed software for SUVI data calibration and assembly of mosaics and assisted with interpretation of data. In fact, our Sun is a rather ordinary star - it's not particularly big or particularly small, it's not particularly young or particularly old. and the Sun has perished out of heaven, and an evil mist hovers over all." e. heating in the chromosphere, Differential rotation of the sun is a. heating in the chromosphere and corona that makes them hotter than the photosphere. 241, 11 (2019). . & Howard, R.
